You are assuming all these deaths are new and ignore the fact that many of these people were probably about to meet a Grim Reaper in the near future. How many were taken by the Covid Reaper instead of the Cancer Reaper or Heart disease Reaper? Covid may have accelerated their demise, the deaths do not contribute to the total death count 1 for 1. See the numbers below—it would be easy to imagine the covid death numbers being stolen from the other causes.
Number of deaths for leading causes of death:(2017)
Heart disease: 647,457
Cancer: 599,108
Accidents (unintentional injuries): 169,936
Chronic lower respiratory diseases: 160,201
Stroke (cerebrovascular diseases): 146,383
Alzheimer’s disease: 121,404
Diabetes: 83,564
Influenza and Pneumonia: 55,672
Nephritis, nephrotic syndrome and nephrosis: 50,633
Intentional self-harm (suicide): 47,173
What makes you think the virus won’t go away by itself?
Smallpox virus didn’t go away by itself. HIV still hasn’t.
As for old people about to die anyway, life expectancy for an 80 year old is 88. Chop them off at 80, they lose 8. Life expectancy is subtle that way. The longer you live, the more disease events you have dodged and so you get years added beyond day-of-birth expectancy (78).
The CDC’s Excess Deaths page tells the tale. Big spikes in most states until lockdown. Then it plummets. Excess deaths are those beyond the average of the same month of prior years.
